【 摘 要 】

Background

Malnutrition is common and affects negatively the health of the older adult. The Mini Nutritional Assessment (MNA), a nutritional assessment tool allows to identify elders malnourished and at risk of malnutrition. The aim of this study is to validate the Portuguese version of the MNA.

Methods

Cross-sectional study with 344 Brazilian elderly. The full version of the MNA was performed, also calf circumference (CC), mid arm circumference (MAC) and body fat (BF). Psychometric evaluation was carried out and correlation, diagnostic accuracy and ROC curves were generated.

Results

Construct validity was supported, all four questionnaire dimensions were evidenced in the Principal Component Analysis and also significant Spearman correlation (P < 0.001) were demonstrated. Criterion validity was also evidenced with relevant sensitivity (MAC = 82.8; CI95% = 64.2-94.2) and specificity (CC = 80.0; CI95% = 74.0-85.1). In the ROC curve AUC was excellent (MAC = 0.832; CI95% =0.785-0.873).

Conclusions

The full MNA demonstrated significant results and sufficient exploratory psychometric properties that supported its validity. It seems to be valid tool to access nutritional status of Brazilian elderly.
